Environmental Services

Environmental services consist of a broad range of services generally having to do with
the assessment, monitoring, and remedy of environmental media suspected to be or
contaminated with chemicals.

Property transfer assessments, or Phase I Environmental Site Assessments (ESAs), can be
conducted to evaluate the environmental condition of a property in advance of a sale or
purchase, to set a baseline of conditions prior to a lease, or to evaluate the condition
of a property after a lease has terminated. EnviroLogic Resources conducts these
assessments using standards developed by the American Society for Testing and Materials
(ASTM). The EnviroLogic Resources team has conducted these types of assessments for real
estate developers, ports authorities, financial institutions, and industry at diverse
types of facilities.

In response to environmental conditions observed during a Phase I ESA or a known
release event, often times soil or ground-water contamination investigations are initiated
to evaluate the nature and extent of the potential problem. EnviroLogic Resources has
conducted these types of investigations at numerous sites involving a variety of
chemicals. The strategy employed by EnviroLogic Resources for these investigations is
focused on the collection of those data critical to developing an understanding of the
risk posed by the site and evaluating potential remedial approaches.

Data collection at a petroleum release site included evaluation of indigenous
microorganisms. The results of the evaluation showed that indigenous microorganisms were
capable of - and in the process of - biologically degrading the petroleum. The regulatory
agency agreed that long-term monitoring and active remediation were unnecessary, saving
the client thousands of dollars.

A tool often used to help formulate monitoring or remedial approaches is ground-water
flow and transport modeling. Modeling can be used in a variety of ways to help reduce
overall project costs. Chemical concentrations at compliance points can be reliably
estimated with a model to support human health risk evaluations. Or, a model can be used
to reduce the capital costs of a remedial system by accurately portraying the ground-water
flow regime, minimizing the number of wells required to remedy the problem. Additionally,
modeling can be used to simulate and evaluate the hydraulic interaction between
ground-water and river systems. EnviroLogic Resources staff members have been involved in
these types of modeling projects and have used several accepted model codes to achieve
results. An important but generally overlooked component of a successful environmental
project is data management. Smooth data handling generates a data set of known quality and
can speed the technical evaluations - the important part of the project! The development
and evaluation of data management systems has been a significant part of the experience
base of the EnviroLogic Resources team.

Risk assessment can be one of the most important aspects of a soil or ground-water
contamination investigation. State regulators are more receptive to these types of
analyses than in years past and the results of an evaluation of risk to human health or to
ecosystems are becoming the basis for many decisions made in the environmental cleanup
process. EnviroLogic Resources personnel have been involved in numerous risk assessments
to support land-use decisions.

At a site contaminated with carcinogenic polynuclear aromatic hydrocarbons (PAHs), a risk
assessment was performed using the specific exposure scenarios that would be expected for
the proposed development - an out-patient medical facility. Site chemical data and the
results of vapor modeling were used as inputs to the risk calculation. The results showed
that remediation of surficial soil would be sufficient to mitigate exposures during
construction - the only pathway with significant risk.

If the end result in the soil or ground-water investigation is that some form of
remediation will be required, the EnviroLogic Resources team can provide remedial
engineering. Soil remedial approaches composed of bioremediation (bioventing, land
farming, and ex situ treatment), soil vapor extraction, solidification, soil washing,
thermal desorption, incineration, as well as the more traditional excavation and disposal
have been evaluated, reviewed, or implemented by EnviroLogic Resources staff.

No one remedial approach can be applied to every site, rather site conditions may favor
one or more remedial systems and it takes an experienced project team to select the most
favorable approach for the conditions at hand.

EnviroLogic Resources personnel have been involved with compliance with many regulatory
programs through the years - from Federal regulatory programs such as:

There are many commonalities among these regulatory programs - the objectives and
general approach, for instance. But it is also key to be able to understand the subtle
differences in the components of the programs and the way they are implemented by each
agency. EnviroLogic Resources can help provide this understanding.

A contaminated site was successfully directed through a regulatory morass involving the
USEPA, Cal/EPA, a State water quality agency, and the county to achieve an effective
investigative and remedial approach. The differing agendas of each agency were identified
and a program was developed that gained approval without performing unnecessary tasks.

EnviroLogic Resources provides litigation support services to our clients through their
attorneys. The development of sound technical arguments to support client positions is
based on thorough understanding of the regulatory and technical issues at hand. The staff
at EnviroLogic Resources is experienced in preserving confidentiality and understands
attorney/client privileges and document retention issues. EnviroLogic Resources is adept
at providing fast-track litigation support services without compromising thoroughness and
creativity. In todays business and regulatory environment, solving complex technical
problems and resolving legal and administrative disputes related to environmental issues
requires the knowledge and skills of recognized experts. EnviroLogic Resources can provide
this expertise.

EnviroLogic Resources staff are experts in environmental project management.
Communication is the key to successful implementation and completion of complex
environmental projects.

Communication is enhanced through the use of project
management software such as MS-Project, development of written project execution
plans, electronic mail, and face-to-face meetings with the client and project team.

EnviroLogic Resources staff members have successfully managed small,
short-duration projects, as well as large, multi-million-dollar investigative and remedial
programs.
